JJ vs TT — Jacks Edge Out Tens

JJ vs TT is a classic adjacent-pair battle where Jacks hold the standard 81.3% overpair advantage. Both hands face similar post-flop challenges with multiple overcards possible, but JJ's one-rank advantage is worth a massive 81% to 19% edge.

Adjacent Pairs: One Rank Makes All the Difference

It may seem surprising that a single rank difference (J vs T) translates into an 81-19 equity split, but this is the nature of overpair vs underpair matchups. The higher pair wins every time both hands fail to improve — which is the majority of boards. The lower pair's only real path to victory is flopping a set (11.8%) or catching a miracle straight, which adds up to roughly 18-19% total equity.

Both Hands Face Overcard Anxiety

What makes JJ vs TT interesting from a strategic perspective is that both hands share the same vulnerability: overcards. JJ has three ranks above it (Q, K, A); TT has four (J, Q, K, A). On overcard-heavy boards, both players face difficult decisions. The difference is that JJ can handle one overcard better (since Q, K, or A are not paired by TT), while TT is in worse shape on almost every overcard board.
